ChatGPT Slides, go try it right now
“Please add each company’s logo next to its name on slide 9.” Claude: “Absolutely not. Do it yourself. It takes a minute. Frankly, I’m disgusted you even asked.” ChatGPT: “Done”

An awesome ship:
Coming soon to a ChatGPT app near you! Don't lose progress, even after restarting the app.

hi all, two things: 1. usage limits are back to being double – your feedback worked 2. we today kicked off an intense sprint to dramatically improve the app simplicity and performance. i will oversee this. more to come. now, send me your complaints
Day 25/ We are doubling all usage limits for all Pro 100/200/500 tiers and Business Premium, effective today. We heard your kind feedback and won’t be reducing usage limits for Pro 200, so your Work and Codex usage will stay the same. We’re also going to continue offering extended limits for dots for now, and usage of your dot will still continue to be separate from your default usage. And we'll of course also keep shipping better models and other efficiency improvements that increase your effective usage over time.

By popular request, you can now text your dot. Give it a task to take off your plate or something to keep an eye on, using text, photos, or even voice notes. It will text you proactively with relevant updates. Safe, secure texting via iMessage or RCS. You’re the only one who can text your dot, and your dot can only text you. Rolling out now as a preview for Pro users in the US.

Day 23/ Much requested iCloud Main & Calendar plugins. Just kidding, today is a reset. Still much requested though!
Much requested, and now yours to connect: iCloud Mail and Calendar plugins are available in ChatGPT. Ask ChatGPT to find that email, catch up on your inbox, check what’s next, or update a calendar event. Phew. Available on all ChatGPT plans on web, desktop, and iOS.

I know it's been a while, but there's a new YouTube video coming on Saturday. I'm finally telling the Cart Surfer origin story.

Once businesses try ChatGPT Work and Space and realise how much more productive it makes its employees- M365 Suite would be in trouble. Microsoft had the Office Suite and exclusive access to OpenAI models. But they just didn't put it together under Notebooks. Now they're introducing Projects and Keeping Notebooks seperate? (just after all the Copilot Consumer Projects were converted to Notebooks) techcrunch.com/2026/10/22/ub…

Dots + Space is a goated combo. Disco, my work dot, has basically implemented the entire Getting Things Done system in ChatGPT Space. He maintains it live based on what's going on across all my work apps and proactively suggests things to take on. This is the most organized I've felt, ever!
